Description

Technical Field

[0001] This invention relates to the field of eyewear technology, and in particular to a head-mounted eye-tracking glasses. Background Technology

[0002] Virtual reality (VR) technology, as an important branch of digital technology, has been widely and deeply applied in various fields such as entertainment, education, industrial simulation, and medical training, becoming a crucial technological means to drive the digital upgrade of these sectors. Head-mounted eye-tracking glasses, as the core device for human-computer interaction in VR technology, rely on eye-tracking technology, which is key to achieving an immersive VR experience. This technology can capture the user's eye movement information in real time, accurately track the user's gaze direction, and adjust and present objects and scenes in the virtual reality world in real time based on the user's gaze point, thereby achieving eye posture recognition and eye movement tracking. With the help of eye-tracking technology, users can complete interactive actions such as selection and operation by gazing at specific points, significantly improving the freedom, participation, and interactivity of the VR experience, making head-mounted eye-tracking glasses an important development direction for VR devices.

[0003] However, existing eye-tracking glasses on the market still have many shortcomings in structural design and actual user experience, making it difficult to meet users' needs: (1) Poor wearability. The existing devices are mostly integrated or simple adjustment structures, which cannot flexibly adjust the size according to different users’ head shape and facial contours. The fit range is narrow, and it is easy to wear too loose or too tight. If it is too loose, the device will fall off. If it is too tight, it will put pressure on the head. Wearing it for a long time will easily cause head fatigue and injury. (2) The wearing comfort is poor. The fit of the contact part between the device and the human face is not reasonable. It lacks a soft and face-fitting structural design. At the same time, the shell does not make adaptive avoidance for the human nose contour, which easily creates hard pressure on the face and nose. In addition, the material selection of the wearing strap is not well considered. The elasticity, tensile strength and tear resistance are insufficient, which further reduces the wearing comfort. (3) Limited scope of application: The existing equipment does not have a structure suitable for people with myopia, and it is not convenient to replace the refractive lenses, making it difficult for people with myopia to use the equipment normally, which greatly reduces the applicable population of the equipment; Secondly, the structure, assembly and reliability of the equipment are insufficient. The assembly method of the shell and the cover is complicated, which is not convenient for disassembly and subsequent maintenance. The core components such as the internal display screen lack effective limiting and positioning structures, which are prone to displacement during use. Moreover, the structural strength design of the shell itself is insufficient, and the edges are easily damaged by external forces, which affects the overall service life and reliability of the equipment.

[0004] In response to the technical problems existing in the current head-mounted eye-tracking glasses, there is an urgent need to develop a head-mounted eye-tracking glasses that is easy to adjust, comfortable to wear, has a wide range of compatibility, and has high structural reliability, so as to overcome the shortcomings of the existing technology and promote the further development of VR eye-tracking glasses technology.
